The literature describes hetaryloxybenzylalkoxyacrylic esters having a fungicidal and, in some cases, also insecticidal, acaricidal and nematicidal action in general form (EP-A 278 595; EP-A 254 426; EP-A 358 692; WO-A 94/19,331, WO-A 94/00,436).

It was an object of the present invention to provide compounds with an improved activity.

Accordingly, we have found that this object is achieved by the compounds I defined at the outset. Furthermore, processes for the preparation of these compounds, compositions comprising them, and their use for controlling animal and fungal pests have been found.

The compounds I are accessible via a variety of methods which are known per se from the literature cited.

For example, the compounds I are obtained by reacting the benzyl derivative II with a hydroxyazole of the formula III in the presence of a base.

L in formula II is a nucleophilically exchangeable group, for example halogen, eg. chlorine, bromine and iodine, or an alkyl- or arylsulfonate, eg. methylsulfonate, trifluoromethylsulfonate, phenylsulfonate and 4-methylphenylsulfonate.

The reaction is conventionally carried out at from 0° C. to 100° C., preferably 20° C. to 60° C.

Suitable solvents are aromatic hydrocarbons, such as toluene, o-, m- and p-xylene, halogenated hydrocarbons, such as methylene chloride, chloroform and chlorobenzene, ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, dioxane, anisole and tetrahydrofuran, nitriles, such as acetonitrile and propionitrile, alcohols, such as methanol, ethanol, n-propanol, i-propanol, n-butanol and tert-butanol, ketones, such as acetone and methyl ethyl ketone, and also ethyl acetate, dimethyl sulfoxide, dimethylformamide, N-methylpyrrolidone, dimethylacetamide, 1,3-dimethylimidazolidin-2-one and 1,2-dimethyltetrahydro-2(1H)-pyrimidine, preferably methylene chloride, acetone, N-methylpyrrolidone and dimethylformamide. Mixtures of these can also be used.

Bases which are generally suitable are inorganic compounds, such as alkali metal hydroxides and alkaline earth metal hydroxides (eg. lithium hydroxide, sodium hydroxide, potassium hydroxide and calcium hydroxide), alkali metal oxides and alkaline earth metal oxides (eg. lithium oxide, sodium oxide, calcium oxide and magnesium oxide), alkali metal hydrides and alkaline earth metal hydrides (eg. lithium hydride, sodium hydride, potassium hydride and calcium hydride), alkali metal amides (eg. lithium amide, sodium amide and potassium amide), alkali metal carbonates and alkaline earth metal carbonates (eg. lithium carbonate, potassium carbonate and calcium carbonate), and also alkali metal hydrogen carbonates (eg. sodium hydrogen carbonate), organometal compounds, in particular alkali metal alkyls (eg. methyllithium, butyllithium and phenyllithium), alkylmagnesium halides (eg. methylmagnesium chloride) and alkali metal alcoholates and alkaline earth metal alcoholates (eg. sodium methanolate, sodium ethanolate, potassium ethanolate, potassium tert-butanolate and dimethoxymagnesium), furthermore organic bases, eg. tertiary amines, such as trimethylamine, triethylamine, triisopropylethylamine and n-methylpiperidine, pyridine, substituted pyridines, such as collidine, lutidine and 4-dimethylaminopyridine, and also bicyclic amines. Substances which are particularly preferred are sodium hydroxide, sodium methanolate, potassium carbonate, potassium methanolate and potassium tert-butanolate.

The bases are generally used in equimolar amounts, in an excess or, if desired, as the solvent.

It may be advantageous for the reaction to add a catalytic amount of a crown ether (eg. 18-crown-6 or 15-crown-5).

The reaction can also be carried out in two-phase systems composed of a solution of alkali metal hydroxides, alkali metal carbonates, alkaline earth metal hydroxides or alkaline earth metal carbonates in water and an organic phase (eg. aromatic and/or halogenated hydrocarbons). Suitable phase transfer catalysts are, for example, ammonium halides and ammonium tetrafluoroborates (eg. benzyltriethylammonium chloride, benzyltributylammonium bromide, tetrabutylammonium chloride, hexadecyltrimethylammonium bromide or tetrabutylammonium tetrafluoroborate) and phosphonium halides (eg. tetrabutylphosphonium chloride and tetraphenylphosphonium bromide).

It may be advantageous for the reaction first to react the hydroxyazole III with the base to give the corresponding hydroxylate, which is then reacted with the benzyl derivative.

Those starting materials II which are required for the preparation of the compounds I which have not already been disclosed in the literature cited at the outset can be prepared by the methods described therein. Those starting materials III which have not already been disclosed in the literature can be prepared by the methods described therein [3-hydroxypyrazoles: J. Heterocycl. Chem. 30, 49 (1993); Chem.

Moreover, the compounds I are obtained by reacting α-ketoesters of the formula IVc in a Wittig or Wittig-Horner reaction {for example with (C₆H₅)₃P⁺—CH₂OR²Cl⁻}, as shown by the equation below (cf. EP-A 534 216).

The keto esters can be obtained by a method similar to known processes [cf. EP-A 493 711; Synth. Commun. 21, 2045 (1991); Synth. Commun. 11, 943 (1981)].

The compounds I can furthermore be obtained by first converting a nitrile of the formula IVa with an alcohol (R¹OH) to the corresponding benzyl ester IVb, as described in EP-A 493 711, and subsequently converting IVb to I, as described in EP-A 203 608.

EP-A 596 692 describes the preparation of the nitrites IVa.

With regard to the double bond, the compounds I can be present in the E and the Z configuration. Both isomers can be used according to the invention, either jointly or separately. Particularly preferred is the E isomer (configuration relative to the carboxylate alkoxy group).

The use forms depend entirely on the intended use; in any case, they should guarantee the finest possible distribution of the active ingredients according to the invention.

When used as fungicides, some of the compounds of the formula I have a systemic action. They can be employed as foliar—and soil-acting fungicides against a broad spectrum of phytopathogenic fungi, in particular from the classes of the Ascomycetes, Deuteromycetes, Phycomycetes and Basidiomycetes.

They are particularly important for controlling a large number of fungi which infect a variety of crop plants, such as wheat, rye, barley, oats, rice, maize, lawn, cotton, soya beans, coffee, sugar cane, grape vines, fruit species, ornamentals and vegetable species, such as cucumbers, beans and cucurbits, as well as the seeds of these plants.

Specifically, the compounds I are suitable for controlling the following plant diseases:

Erysiphe graminis (powdery mildew) in cereals,

Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits,

Podosphaera leucotricha in apples,

Uncinula necator in grape vines,

Puccinia species in cereals,

Pyricularia oryzae in rice,

Phytophthora infestans in potatoes and tomatoes,

Fusarium and Verticillium species in a variety of plants,

Plasmopara viticola in grape vines,

Alternaria species in vegetables and fruit.

The novel compounds can also be employed in the protection of materials (wood), eg. against Paecilomyces variotii.

They can be converted into the customary formulations, such as solutions, emulsions, suspensions, dusts, powders, pastes or granules. The use forms depend on the specific intended purpose; in any case, they should guarantee the finest possible distribution of the active ingredients.

The formulations are prepared in a known manner, eg. by extending the active ingredient with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents as auxiliary solvents if water is used as the diluent.

Suitable auxiliaries are essentially the following:

solvents, such as aromatics (eg. xylene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. mineral oil fractions), alcohols (eg. methanol, butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine, dimethylformamide) and water;

carriers, such as ground natural minerals (eg. kaolins, clays, talc, chalk) and ground synthetic minerals (eg. highly-disperse silica, silicates);

emulsifiers, such as nonionic and anionic emulsifiers (eg. polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates), and

dispersants, such as lignosulfite waste liquors and methylcellulose.

Suitable surfactants are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, eg. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl- and alkylarylsulfonates, alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols, and of fatty alcohol glycol ether [sic], condensation products of sulfonated naphthalene and its derivatives with formaldehyde, condensation products of naphthalene, or the naphthalenesulfonic acids, with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl polyglycol ethers, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignosulfite waste liquors or methylcellulose.

Aqueous use forms can be prepared from emulsion concentrates, dispersions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, substrates as such, or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is also possible to prepare concentrates comprising active ingredient, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, which are suitable for dilution with water.

Powders, materials for spreading and dusts can be prepared by mixing or grinding the active ingredients together with a solid carrier.

Granules, eg. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers.

Solid carriers are mineral earths, such as silica gel, silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powder or other solid carriers.

Depending on the nature of the desired effect, the application rates are from 0.02 to 3 kg of active ingredient per ha, preferably 0.1 to 1 kg/ha.

In the treatment of seed, amounts of active ingredient of from 0.001 to 50 g, preferably from 0.01 to 10 g, are generally required per kilogram of seed.

Under open conditions, the application rate of active ingredient for the control of pests is from 0.02 to 10, preferably 0.1 to 2.0, kg/ha of active ingredient.
